Head Encircling Sensory Deprivation Pillow

ABSTRACT

A sleep-enhancing device comprising an elongated pillow that wraps around the eyes and ears of the user and is thick enough to enable the user to rest their head on a hard surface without any part of their face touching the hard surface.

CROSS-REFERENCE TO RELATED APPLICATIONS

The present application is a continuation-in-part of application Ser. No. 13/389,240, filed Feb. 6, 2012, which is incorporated herein by reference.

BACKGROUND

1. Field of the Invention

The present invention generally relates to pillows; more particularly, the present invention relates to sleep-enhancing devices for resting a user's head while occluding light and sound during use.

2. Background

A full and restful sleep period is necessary to a full and productive waking period. However, an individual often sleeps in a situation that is uncomfortable, bright and/or noisy. For example, traveling businesspeople often find it necessary to sleep in loud, bright and uncomfortable airplanes, and college students often find it necessary to nap and/or sleep at their library tables, desks or student centers. Unfortunately, the sleep achieved in such situations is often interrupted by light, noise and discomfort, thereby limiting the benefits of the sleep period.

Many devices have been invented with the intention of occluding sleep-distracting stimuli, including light and noise. For example, U.S. Pat. No. 2,537,768 to Laporte (“Laporte”), which is entirely incorporated herein by reference, teaches an eye mask with a strap means of securing around a user's head, to which are attached ear plugging means. While the device of Laporte occludes both light and sound, the device requires that unsanitary and uncomfortable earplugs be inserted into the user's ears, and further fails to provide any means of padding for the user's head, thereby necessitating the user to use a separate expensive and bulky pillow device to attain comfortable conditions for sleep.

U.S. Pat. No. 5,343,561 to Adamo (“Adamo”), which is entirely incorporated herein by reference, teaches an eye mask with a method for attachment around a user's ears. Although this device can occlude sound, its elastic means of attachment is impractical and uncomfortable. The device of Adamo also discloses a separate “U” shaped device to be worn around a user's neck to provide neck support. However, the “U” shaped device is limiting in the variety of sleeping positions it affords a user, and would be of little use if it were to be displaced in sleep. Further, having two separate units is inconvenient to pack and transport, expensive to manufacture and complicated to use.

A number of inventions have disclosed devices that can both insulate a user from sleep-distracting events, including noise and light, while providing concurrent padding for a user's head. For example, U.S. Pat. No. 6,651,256 to Swift (“Swift”), which is entirely incorporated herein by reference, teaches a wearable pillow device to be worn in the manner of a helmet. The device of Swift incorporates a light-occluding portion and a head-surrounding pillow portion. However, this device is bulky, expensive to manufacture, complicated to wear and impractical to transport and use. Further, this device is supplemented by a “U” shaped pillow portion to support a user's head, thereby limiting the variety of the user's possible sleeping positions.

As another example, U.S. Pat. No. 6,088,836 to de Cordova (“de Cordova”), which is entirely incorporated herein by reference, teaches a sleep enhancing device to be worn around a user's head, the device having a light occlusion portion attached to a padded head rest wrap-around pillow portion. While de Cordova teaches a means of light and noise occlusion and a means of padding for the sides and back of the user's head, its construction is complicated and expensive to manufacture. Further, its design requires that it be worn in strict orientation on a user's head, and as such, its effectiveness is compromised when displaced during sleep. Most importantly, the device of de Cordova fails to provide a means of padding for the front portion of a user's head, rendering the device ineffective and uncomfortable for a user sleeping in a position in which the front portion of the user's head and face, such as the user's forehead, ocular regions, nasal regions, cheekbones and temple regions, are resting against a firm surface (e.g., desk).

Generally, there are limitations associated with prior art sleep-enhancing devices. For example, prior art sleep enhancing devices are uncomfortable and complicated to use, inconvenient to transport, expensive to manufacture, can be rendered ineffective if shifted during use, and can fail to provide sufficient padding for a user's head during use.

There is thus a need for improved sleep enhancing devices.

SUMMARY OF THE INVENTION

An object of the present invention is to provide a sleep-enhancing device that provides comfort for a user who is resting their head on a hard surface.

Another object of the present invention is to provide a sleep-enhancing device that blocks any light from entering the user's eyes.

Another object of the present invention is to provide a sleep-enhancing device that blocks some sound from entering the user's ears.

The present invention comprises an elongated pillow that is of a sufficient length to fully encircle a user's head, where the elongated pillow has an outer shell of a generally tubular shape and a soft stuffing material on the interior of the outer shell, as well as fasteners on each end of the pillow to fasten it around the user's head. The elongated pillow covers the user's eyes without allowing any light to leak in around the user's nose or at any other location. The elongated pillow is thick enough when compressed by the weight of a user's head that it allows the user to rest their head on a hard surface (such as a desk or a table) without any portion of the user's face touching the hard surface.

In an embodiment, the pillow portion completely prevents light from entering the user's eyes while in use and conforms to the shape of the user's nose sufficiently to prevent light leakage around the nose.

In any embodiment of the present invention, it is preferable that the pillow portion have enough thickness so as to pad the user's head adequately when the user is resting his or her head on a hard surface (such as a table or a desk). Since a human head provides a force of about 45N when resting on a hard surface, this means that the compressed thickness of the pillow portion should be at least 1.5 cm or greater. When the pillow portion is uncompressed, it should be thick enough to block at least 8 dB of sound from reaching the user's ears—typically, this should be at least 8 cm thick, though this depends on the type of fill and the density of the fill.

The material of which the exterior of the pillow portion is made is preferably polyester fleece. It may also be made of any other woven or nonwoven fabric as long as it is sufficiently strong and soft for the purpose and does not irritate the skin. For example, polyester, cotton, linen, nylon, broadcloth, buckram, bunting, calico, corduroy, silk, satin, rayon, neoprene, acrylic, acetate, Spandex, Lastex, Kevlar, or velvet may be used.

The material filling the pillow portion is preferably an ultra-fine polyester fiber fill. It could also be any other material suitable for filling pillows as long as it is soft and compressible. For example, synthetic or natural fiber fill, shredded foam, memory foam, feathers or feather blends, Styrofoam beads, cotton, foam, down, cloth scraps, or air may be used.
